摘要： PROBLEM TO BE SOLVED: To provide a promotor material for purifying automobile exhaust gas having high oxygen storage capability at a comparatively low temperature, capable of purifying the exhaust gas at high efficiency from a state at a comparatively low temperature by a carried catalytic active substance.SOLUTION: Since a solid solution ratio K of ceria 16c and zirconia 16a is 30-90%, an oxygen release peak temperature of a ceria-zirconia material 16 is lower in comparison with, for example, a uniform conventional solid solution type in which ceria 16c and zirconia 16a are uniformly solid-solved, to thereby heighten oxygen storage capability at a comparatively low temperature. The ceria-zirconia material 16 has a core-shell structure in which the core is formed of zirconia 16a, and ceria-zirconia 16d and ceria 16c exist on the surface of the core. Since the surface of the ceria-zirconia material 16 has cerium-rich property, very high activity can be obtained when carrying platinum 14, to thereby enable highly efficient purification of exhaust gas from a state at a comparatively low temperature.
摘要翻译：要解决的问题：提供一种用于净化在较低温度下具有高储氧能力的汽车废气的促进剂材料，其能够通过携带的催化活性物质从较低温度的状态高效地净化废气。解决方案：由于二氧化铈16c和氧化锆16a的固溶比K为30-90％，与例如均匀的常规固溶体类型相比，二氧化铈 - 氧化锆材料16的氧释放峰温度较低，其中二氧化铈 16c和氧化锆16a均匀地固溶，从而在相对低的温度下提高储氧能力。二氧化铈 - 氧化锆材料16具有核 - 壳结构，其中芯由氧化锆16a形成，并且二氧化铈 - 氧化锆16d和二氧化铈16c存在于芯的表面上。由于二氧化铈 - 氧化锆材料16的表面具有富铈特性，因此在携带铂14时可以获得非常高的活性，从而能够从较低温度的状态高效地净化废气。
